摘要： A method for processing network traffic data includes receiving a packet, and determining whether the packet is a previously dropped packet that is being retransmitted. A method for processing network traffic content includes receiving a plurality of headers, the plurality of headers having respective first field values, and determining whether the first field values of the respective headers form a first prescribed pattern. A method for processing network traffic content includes receiving a plurality of packets, and determining an existence of a flooding attack without tracking each of the plurality of packets with a SYN bit.

摘要： A method for determining a type of content includes receiving a first packet, determining a state of classification for the first packet or for a session with which the first packet is associated, receiving a second packet, and determining a content type for the second packet based at least in part on the determined state. A method for determining a type of content includes receiving a packet associated with a session, determining whether a content type has been determined for the session or for an other packet associated with the session, and classifying the packet to be the content type based at least in part on a result from the act of determining. A method for determining a type of content includes receiving a first packet from a first port, the first port adapted for receiving at least two types of content, and determining a content type for the first packet or for a session with which the first packet is associated. A method for determining a type of content includes receiving a packet associated with a session, and determining a state of classification for the packet or the session.
